Macnamara's Ford "triumph" was the Edsel. I thought it was a nice-looking car, but it flopped. Basically, there wasn't room in the market between Ford's Fairlane 500 and the Mercury line.......and I also was told at the time that the Edsel had a Freudian front end design that didn't connote masculinity as well as it might (harrumph!). The model was withdrawn after the 1960 model year. Its "seagull" tail fins were echoed in the 1959 and 1960 Chevy and the 1960 Ford. Macnamara was also the originator of the idea for the TFX, which flopped as a joint Navy/Air Force light bomber but survived and had a decent career as the F-111 "Aardvark", which is still in service with Australia.

McNamara was an instructor in statistics. Period. In his book he tries to say his life was in danger during his duty for his country because a plane similar to one he occasionally traveled on crashed in Spain.
